Paul Merson’s warning over Oliver Glasner and Man Utd
Paul Merson, the respected football expert and Sky Sports columnist, has issued a stark warning regarding the potential appointment of Crystal Palace manager Oliver Glasner at Manchester United. Despite Glasner’s remarkable achievements with Palace, Merson argues the Austrian’s preferred tactical system may clash with the current United squad’s strengths.
Glasner has earned widespread acclaim for leading Palace to FA Cup glory last season and lifting the Community Shield this campaign. His side boasts an extraordinary 18-game unbeaten run, including a dramatic victory over Liverpool, showcasing impressive cohesion and tactical discipline.
The three-at-the-back system: A double-edged sword?
Merson points out that Glasner operates primarily with a three-at-the-back formation — a system that Palace’s squad is well equipped to execute. He highlights how Palace’s defenders, wing-backs, and midfielders fit this system perfectly, allowing them to control games effectively.
However, Merson expresses concern that this approach does not align with Manchester United’s current player profiles. "It's being proven that it is a system that just doesn't fit the players at Man Utd," he says, cautioning that Glasner might struggle to adapt his preferred style to the demands and personnel of Old Trafford.
Examples of formation adaptability
Glasner himself has stressed the importance of tailoring the system to the squad. Throughout his career, he’s used formations ranging from 4-4-2 to 3-4-3 and 4-2-3-1, adapting to the players at his disposal. Yet, Merson remains sceptical about whether this adaptability will be sufficient at United, especially given the club’s recent struggles under Ruben Amorim, who also favours a three-at-the-back system.
Why the fit matters at Manchester United
Manchester United’s history and stature mean any managerial appointment faces intense scrutiny. Merson notes that while Glasner’s calm and measured approach has served Palace well, the pressure at United is on a different scale. The club’s fanbase and media demand immediate success, and tactical mismatches can exacerbate performance issues.
Ruben Amorim, the current United boss, retains backing from minority shareholder Sir Jim Ratcliffe, who is keen to give Amorim a full season to prove himself. Yet, the growing external pressure has sparked speculation about Glasner as a potential successor if the job falls vacant.
Man Utd’s squad and tactical challenges
United’s players have struggled to gel in a three-at-the-back setup. The squad lacks the specific wing-backs and defensive midfielders needed to excel in this formation, unlike Palace. This mismatch has contributed to inconsistent performances, including recent disappointing defeats like the one against Brentford.
Crystal Palace’s extraordinary run under Glasner
Under Glasner’s guidance, Palace have not only secured trophies but have become a formidable force in the Premier League. Their 18-game unbeaten run is a testament to the team’s organisation and resilience. Merson highlights that Palace’s success is not down to luck; the team consistently controls matches and applies tactical discipline.
Jean-Philippe Mateta, Palace’s centre-forward, exemplifies this system’s effectiveness. Merson praises Mateta as a player who could make a difference for bigger clubs like United, describing him as "an absolute handful who leads the line brilliantly." The wing-backs and midfielders also contribute significantly, providing both defensive cover and attacking support.
Managing expectations at Palace and United
Merson advises Palace fans to savour the current success without setting unrealistic targets. Comparisons with Arsenal’s long unbeaten runs show how remarkable Palace’s achievement is, but he cautions that the Premier League’s demanding nature means the run will eventually end. Still, Palace should aim to finish comfortably in the top half and build steadily.
By contrast, at Manchester United, the expectation is always to compete for titles. The tactical system must suit the players and deliver results immediately. This presents a challenge for any manager, including Glasner, who might be tempted by the prestige of the United job but face difficulties in implementing his preferred tactics.
Conclusion: The dilemma of fit versus opportunity
While Oliver Glasner’s work at Crystal Palace is highly impressive, Paul Merson’s analysis raises important questions about whether United are the right fit for his style. The three-at-the-back system, so successful at Palace, may not translate to Old Trafford without significant squad adjustments.
Yet, the allure of Manchester United is undeniable. Merson reflects on how few managers can refuse an offer from one of the world’s biggest clubs, despite the risks involved. The decision for Glasner would be complex — balancing the chance to manage at the highest level against the tactical challenges and pressures of the United environment.
